摘要：

The dynamic viscosity of n-decane and methane mixtures containing 31.24, 48.67, 60.00, 75.66 and 95.75% (mol%) of methane has been measured using a falling-body viscometer. The measurements ( 295 data points) have been performed in the temperature range 293.15 to 373.15 K and at pressures up to 140 MPa for viscosity. The data have been used to calculate the excess activation energy of viscous flow using a mixing law. Moreover, a self-referencing model, previously developed in the laboratory, gives an average absolute deviation of the viscosity of about 3% with a maximum deviation of 16%.
